As shown on the drawings:

The reference numeral 1 indicates a base plate or block forming a partof a fountain pen desk set with said base plate provided with a passageor opening extending through the base plate from top to bottom anddesignated by the reference numeral 2. The lower end of the passage oropening 2 at its lower end is enlarged to form a groove or recess 3. Theopening in the base member 1 is provided for the reception of a clampingor supporting unit comprising an internally threaded sleeve 4 having aperipheral flange 5 integrally formed on the lower exterior rtionthereof. Projecting downwardly into the passage 2 and adjustablythreaded into the internally threaded sleeve 4 is an exteriorly threadedhollow sleeve or shank 6 which is integrally formed on the under side ofa clamping head or plate 7. The externally threaded shank 6 and theclamping plate 7 form a clamping bushing which is adapted to be tightlythreaded into the base sleeve 4 and against the top surface of the basemember 1 to provide a rigid support for the swivel joint mechanism.

Projecting downwardly through a central opening in the clamping plate 7of the bushing member is a post or stem 8 having a collar 9 integrallyformed on the upper portion thereof and adapted to rest on the plate 7.The stem 8 is rotatably engaged in the bushing plate or head 7 and has acoiled spring 10 engaged around the body portion thereof with the upperconvolution of the spring contacting the inner surface of the head 7.The lower end of the control spring 10 seats upon a washer or ring 11which is engaged around the stem and is supported by means of a pin 12which projects diametrically through the stem. The spring 10 acts toresiliently hold the collar 9 of the stem in contact with the head ortop plate 7 of the bushing member of the base unit of the swivel joint.Integrally formed on the collar 9 is a supporting fork or U-shapedbracket comprising a cross-piece or base member 13 having integrallyformed on the ends thereof parallel arms 14. Each of the arms 14 has theupper end thereof terminating in an apertured disc or ring 15. Theapertured arms of the supporting fork are provided for the purpose ofreceiving and supporting a sectional swivel unit or knuckle in itscompleted form having the shape of a barrel. The adjustable swivel unitor knuckle conr prises an intermediate member or middle sectioncomprising an axially passaged body section 16 having an internallythreaded radial recess or pocket 17 formed in the outer peripheralsurface thereof for removably receiving a threaded stud 18. The threadedstud 18 is integrally formed on the lower end of a metal base 19 of afountain pen or scribing instrument receiving socket 20 provided with asuitable receiving pocket for the removable reception of a writing pen21 or the like. The socket 20 may be constructed of hard rubber,bakelite or any other suitable material or, if preferred, the socket maybe constructed of metal, in which case the base 19 may be integral withthe body portion of the socket. 1

The body portion of the barrel shaped swivel joint is adapted to beositioned between the apertured disc 15 of the rotatable fork member andis rotatably supported on a hollow shaft or stem 22 which is integrallyformed axially on the inner end of a barrel head 23, the inner end ofwhich is providedwith a. round recess 24 and with a notch 25 as clearlyillustrated in Figure 4 to permit the barrel head to engage over andenclose one of the apertured discs 15 and one of the arms '14 of therotatable fork member. When the internally threaded sleeve 22 projectsthrough the opening of the two discs 15 of the fork member the barrelhead 23 is adapted to engage over one of the discs 15 with the armportion of said disc engaged in the notch 25 thereby holding the barrelhead 23 against rotation with respect to the forked member.

Removably engaged on the projecting end of the internally threaded shaft22 to the outside of the second apertured disc 15 of the forked memberis a barrel washer section 26 having a middle opening 27 to engage overthe hollow shaft 22 and also provided on its inner side with a circularrecess or opening 28 and a notch 29 as clearly illustrated in Figure 5.The barrel washer section 26 is thus adapted to be engaged on the hollowshaft 22 to seat over the second disc 15 and its arm 14 to hold thewasher section against rotation with respect to the forked member.

The barrel head 23 and the barrel washer section 26 when in positioncontact the end surfaces of the middle section or body portion 16 of thebarrel shaped swivel unit. For the purpose of holding the barrel head 23and the barrel washer section 26 clamped or frictionally engaged againstthe outer or end surfaces of the barrel middle section 16 an adjustablebarrel head or end barrel section 30 is engaged to the outside of thewasher section 26 by means of a screw stem 31 which is integrally formedaxially on the inner side of the end barrel section or head 30, asclearly illustrated in Figure 3.

The threaded stem or screw 31 is adapted to be threaded into theinternally threaded sleeve or shaft 22 of the barrel head section 23thereby clamping or securing the various barrel sections in contact withone another to complete the swivel barrel shaped joint and hold themiddle section 16 of the barrel on which the end socket is supported infrictional engagement between the disc members 15 of the fork unit. Byadjusting the screw stem 31 of the barrel head 30 with respect to theinternally threaded shaft 22 of the barrel head 23 the arm portions ofthe rotatable forked unit are adjustably compressed or released withrespect to the side surfaces of the middle section 16 of the barrelunitto middle barrel section 16 to be pivotally adjusted into differentpositions.

It will thus be noted that an improved swivel joint has been devisedwherein the joint unit takes the form of a barrel and permits the penreceiving socket to be pivotally adjusted on the hollow shaft 22 of thebarrel unit while the barrel unit together with the socket supportedthereon is adapted to be ro-- respect to one another and wherein therotatable fork portion is adapted to be rotated with respect to the basesection 7 so that there is no wear on the material forming the baseblock 1 of the fountain pen desk set.

The spring controlled fork unit on which i the barrel shaped swiveljoint is supported is permitted to have slidable movement with the basemembers 7 and 4 with the spring 10 serving to resiliently hold thecollar 9 of the fork unit in contact with the top surface of the cap ortop unit 7 of the base section.

The barrel unit on which the pen receiving socket :20 is supported isarranged so that the middle section of the barrel is adapted to berotated on the hollow shaft 22 to permit the socket to be pivotallyswung with respect to the fountain pen desk setblock or base section 1while the entire barrel unit together with the socket is adapted to berotated with the fork unit which is pivotally supported on the clampingmember 7 forming a part of the base portion of the socketsupportingunit. It will thus be noted that an improved swivel pointdevice has been provided permitting universal movement of the pensupporting socket and obviating wear of the base block 1 since thearrangement is such that there are no moving parts coming in contactwith the base block or base section 1. r

It will of course be understood that various details of construction maybe varied through a wide ran e without departing from the principles 0%this invention, and it is therefore not the purpose to limit the patentgranted hereon otherwise than necessitated by the scope of the appendedclaims.
